Blue-Light Filtering
What do blue-light filtering glasses do for my child?
What do blue-light filtering glasses do for my child?
Phones, tablets, computers, gaming consoles and TV all give off blue light, and today's kids spend more hours in front of screens than any generation before them. Square Eyes lenses filter a portion of this blue light, adding a simple layer of support during everyday screen use. They're built for real use: homework, gaming, weekend cartoons, whenever a screen is out.
Why does evening screen time matter?
Why does evening screen time matter?
As natural daylight fades, your child's body starts easing toward sleep, right as evening homework, gaming or a last show before bed tends to happen. Blue-light filtering lenses may help support that natural wind-down when worn during evening screen use. It's a simple layer of support for the part of the day screens are hardest to avoid.
Can they help with screen-tired eyes, and what's the 20-20-20 rule?
Can they help with screen-tired eyes, and what's the 20-20-20 rule?
Long stretches on a screen can leave anyone's eyes feeling tired or strained, kids included. Square Eyes lenses may help with mild screen-related discomfort. Pair them with the 20-20-20 rule: every 20 minutes, look at something roughly 20 feet (about six metres) away for at least 20 seconds. Two simple habits, working together.
Is this about limiting screen time?
Is this about limiting screen time?
No. Screens are part of modern childhood, for school, gaming and staying in touch with friends. Square Eyes isn't about rules or cutting back. It's practical support for the screen time your family already has, without judgement.
UV400 + Growing Eyes
Why is UV400 the real headline feature of Square Eyes glasses?
Why is UV400 the real headline feature of Square Eyes glasses?
UV400 is one of the most important protections built into every Square Eyes pair, blocking UVA and UVB wavelengths right up to 400 nanometres, the full range of UV that can affect the eyes. The best protection is protection children actually want to wear, so we've built that level of defence into frames kids actually want to wear.
Why do children need more UV protection than adults?
Why do children need more UV protection than adults?
A child's eyes are still developing, with a natural crystalline lens that's far clearer than an adult's, letting more UV travel deeper into the eye. The World Society of Paediatric Ophthalmology and Strabismus reports that, specifically at the 320 nanometre UV wavelength, transmittance through the lens sits around 20% at birth, falling to just 2 to 3% by age 20. It's one specific measure, not a total UV figure, but it points to the same conclusion: young eyes let through significantly more UV than adult eyes, which is why UV400 protection matters from an early age.
Does UV really add up over time, and is it that strong here?
Does UV really add up over time, and is it that strong here?
Yes, on both counts. UV damage builds gradually over a lifetime, and long-term exposure is linked to conditions including cataracts and pterygium. New Zealand's peak UV Index runs around 40% higher than comparable Northern Hemisphere latitudes (Earth Sciences New Zealand/NIWA), and Australia regularly sees Very High to Extreme UV through summer. UV is invisible, and can still reach damaging levels on cool or cloudy days, reflecting off water, sand and concrete too. Starting protection early gives your child's eyes cover for the years they need it most.
Does a dark tint mean better UV protection?
Does a dark tint mean better UV protection?
No, and this is worth knowing: UV protection comes from the lens itself, not how dark it looks. A dark tint alone does not guarantee UV protection, while a clear lens can carry full UV400 protection. Square Eyes lenses are Category 0 (clear, no glare reduction) and carry full UV400 protection built in, giving your child meaningful everyday protection. In harsh sun, glare or snow, suitable sunglasses and a hat add extra coverage on top.
Product + Fit
Can my child wear them all day?
Can my child wear them all day?
Yes. Square Eyes is built for everyday, all-day wear, at school, on screens, outside, wherever the day takes them. No special routine required, just glasses that work whenever they're on.
What age and size should I choose?
What age and size should I choose?
Square Eyes suits children roughly 5 to 13, with three fits built around how kids' faces actually grow: Smaller, Standard and Larger. Our size guide makes it easy, or simply compare the measurements to a pair your child already wears comfortably.
Can I add my child's prescription?
Can I add my child's prescription?
Square Eyes lenses are non-prescription. For prescription needs, your optometrist can advise whether prescription lenses can be fitted into a Square Eyes frame.
What are they made from, and how do I care for them?
